Abstract (en)
[origin: US2020293761A1] Embodiments of this application disclose a facial recognition method performed at a server. The method includes: obtaining a to-be-recognized facial image and extracting a target eigenvector of the facial image; calculating a distance between each target eigenvector and a mean vector corresponding to each facial identifier to obtain a first distance set, and determining a first recognition result corresponding to the facial image and a corresponding first score according to each first distance set; calculating a distance between each target eigenvector and each eigenvector corresponding to each facial identifier to obtain a second distance set, and determining a second recognition result corresponding to the facial image and a corresponding second score according to each second distance set; and determining a facial recognition result for the facial image and a corresponding score according to a comparison of the first and second recognition results and the first and second scores.
